ERNEST COLEGATE, 0F LONDON, ENGLAND.

sNAr-rAsTENEn To all 'whom t may concern.'

' 'Be it known that I, ERNEST COLEGATE', a subject of the King ofEngland, andrresiding at London, in England, have invented 5 certain newv and useful Improvements in Snap-Fasteners, of which the following is aspecification.

This invention relates to snap fasteners and 'particularly to the socketportions of those fasteners intended to be a-ttachedto envelops, apasteboard, xboxes, paper fabric,

. and similar substances. Such socket por tions are not intended torelease the corref sponding stud member when the latter has once. beenmade to engage therewith.-

Thev object of this invent-ion is to provide,

a socket of this type which may be cheaply made and easily assembled.

According to this invention the socket porf tion comprises a base platehaving spiked projections which are bent at right angles to the' planeof the plate, their lower portions being'b'ent o-ver the fiange of anannul'r cover, thereby connecting the cover the "base plate, the pointedends of allthe spikes subsequently serving to rangement can be morequickly assembled together prior to its Vbeing attachedv tov itsAsupporting surface.

In the accompanying drawings which show one construction of socketmember in accordance with this invention, Figure l is a vertical sectionthrough the cove-r, Fig. 2 is a similar View of the spring member. Fig.3 -is a plan of the `base plate 4before the spikes thereon have beenbent upward. Fig.

4 is a section through a socket member after the parts have beenassembled, Fig. 5 is a perspective view of a completed socket member,and Fig. 6 is asimilar view showing the socket member riveted to a stripof paper or the like.

In all the figures the socket member is representedof a size larger thanthatusually employed.

The' annular cover from sheet metal and has a flange A sur. rounding itsannular recessed portion.

or casing A is stampedA Adapted; to lie within the cover isan innerspring' member B comprising an annular cup having spring fingers Badapted t0 engage the stud portion of the fastener (not shown). Thematerial from which the spring fingers are made is preferably such that`they cannot be bent back after once engaging the stud. That is the'snapfastener of which the socket member herein described is a part is of thetype orclass styled.non-separable. In the particular embodlment of theinvention illustrated the outer end wall ofthe cover A is in directcontact with the spring fingers B so that it acts as a positive stop tomovement of the fingers in the direction necessary to release the studmember. The-base plate C is also stamped from sheet metal and, in theconstruction illustrated, has four spikesl C pro-A jecting therefrom.The lower portions of thespikes nearest the edge. of the baseplate arefirst bent over the flange A ofthe cover, thus unit-ing the componentparts together and forming a socket having spikes projecting vertically'from its flange suit-Y able for attachment to paper or the like. Theprojecting ends of all the spikes C are subsequently passed through andriveted over on to thesupporting surface of paper, cardboard, linen orthe like D as shown in Fig. 6, the paper being first perforated toreceive the projecting portion of the cover A in the usual manner.'

In the construction illustrated the base plate is provided with a smallcentral aper- Lture C2 to facilitate the assembly of the parts, butthedepth of the recess in the cover A is suihcient to permitof the studportion of the socket engaging the latter without having to make contactwith the base plate which thus serves as a shield to prevent the springmembers B being tam-- pered with when the socket is attached to articlesof such a nature that its rear surface is exposed. It will be understoodthat the number of projecting spikes employed willl varv inaocordancewith the purpose for which the fastener is intended.

What I claim as my invention and desire 'to secure by Letters Patentis':

.1. The herein described socket member of a snap fastener comprising abase plate, an annular cover having at one end an aperture through whichthe stud member of the fastener passes-to engage the socket portion atits opposite end an outwardly projectin flange that bears against thebase plate, an spurs on the base plate'bent over said ange to connectthe component$- parts of'the socket together, with'the pointed extremityof e'ach projectin and constituting means for securing the completedsocket to a sup ort.

2. The herein described socket mem er 0f fastener comprising a hollowcover section having a laterally projectin lar iiange at one end andprovide other end-with an. aperture through which the stiid member vofthe fastener is adaptedA to extend, a base plate bearing liange of theagainst. the cover section and havinga -pluralityfof s urs whichare'bent over and `against s'ai 1n" theirlength, .to secure the covervsection the free ends of saidspurs engage fthe 'stud member of thefastener when ,it is linserted in the 3.
